Choosing the Right Protein Powder Without the Overwhelm: A Guide for Women Over 40

If you’ve ever stood in a health food shop or browsed online wondering which protein powder to buy, you’re not alone. The variety can feel endless, and when you're already dealing with fatigue, brain fog, or weight gain in your 40s or 50s, making this one decision can feel like a mental workout in itself.

Many of the women I work with know they need more protein but the confusion around which powder to choose often leads to doing nothing at all. Let’s change that.

This guide is designed to help you feel clear and confident about choosing the best protein powder for your needs, without the overwhelm.

Why Protein Matters More After 40

As we move through perimenopause and menopause, our muscle mass naturally declines, and our protein needs increase. Protein is essential not just for muscle tone, but also for hormone regulation, immune function, skin repair, and blood sugar balance.

If you’re not getting enough protein, you may notice more fatigue, sugar cravings, difficulty with weight loss, and even more noticeable signs of ageing in your skin and hair. This is why so many women benefit from adding a high-quality protein powder to their daily routine.

Types of Protein Powders – What to Consider

1. Whey Protein (Dairy-Based)

Whey is an animal-based protein and naturally contains all nine essential amino acids, making it a complete protein. It’s rich in leucine, the amino acid most associated with muscle repair and preservation.

But it’s not for everyone. If you're sensitive to dairy or prone to digestive issues, this may cause bloating or discomfort. Some women also dislike the thicker texture. A lighter, “clear” version is available on the market and can be easier to tolerate.

2. Egg White Protein

Egg white protein is a dairy-free option that still provides a complete amino acid profile. It’s generally well tolerated and often easier to digest than whey, making it a great choice for those who want an animal-based option without the dairy.

3. Pea Protein

Pea protein is a popular plant-based choice that’s naturally rich in iron and has a neutral flavour. However, it may not always provide enough leucine per serving, so check the label. Some women also find it a bit harder to digest.

4. Pea and Rice Blend

This combination is often more balanced because the amino acids that pea protein lacks are present in rice protein, and vice versa. If you’re looking for a plant-based, vegan-friendly and more complete option, this blend works well.

5. Collagen Powder

Collagen is brilliant for skin, joints, and connective tissue, but it’s not a complete protein. It lacks tryptophan, which means it won’t support muscle repair or overall protein needs. Think of collagen as a bonus for your skin and joints, not your main protein source.

What to Look for When Buying Protein Powder

Before you commit to that tub of powder, ask yourself the following:

• Can you try a sample first?
  Some companies offer single-serve packets. It’s best to test taste, texture, and tolerance before investing in a large tub.

• Is there at least 2.5g of leucine per serving?
  This is the minimum needed to trigger muscle protein synthesis. If it’s not on the label, ask the brand or choose another that clearly shows the amino acid breakdown.

• Are the ingredients clean?
  Aim for minimal ingredients. Avoid artificial sweeteners, colours, or additives you don’t recognise.

• Does it suit your lifestyle?
  If you’re plant-based, dairy-free, or have sensitivities, there’s a protein powder for you—but always read the label to ensure it's the right fit.

• Is it third-party tested?
  Especially important with plant-based powders to ensure they're free from heavy metals and contaminants.

How Much Protein Do Women Over 40 Really Need?

This is one of the most common questions I get and one that doesn’t have a one-size-fits-all answer. There’s a lot of conflicting information out there, which can make it confusing. Some sources offer very conservative daily targets, while others especially in functional medicine and sports nutrition recommend a much higher intake to support ageing, hormonal changes, and muscle preservation.

What’s clear is this: your protein needs change as you age. As oestrogen declines, so does muscle mass, bone strength, and metabolic function. This makes adequate protein intake even more important for women in their 40s and beyond.

So, what do the experts say?

🔹 European guidelines such as those from the PROT-AGE Study Group recommend 1.0–1.2 grams of protein per kilogram of body weight daily for healthy older adults, and up to 1.5 g/kg for those who are active or at risk of muscle loss.

🔹 In the functional medicine space, experts often recommend more. Dr Mark Hyman, for example, suggests that many women over 40 benefit from around 1.6–2.0 grams of protein per kilogram of body weight per day, especially if they are trying to lose weight, balance hormones, or maintain muscle. In his own words:

“Most women are not eating enough protein. For body composition, blood sugar control, and metabolic health, I recommend aiming for at least 100g of protein a day for most women over 40.”
— Dr Mark Hyman, Young Forever (2023)

That might sound like a lot but when you space it across the day, it’s entirely doable. For example, aiming for 30–35g of protein at breakfast, lunch, and dinner is a great starting point.

It’s also important to listen to your body. You might need more protein if you:

• Are experiencing muscle loss or weakness

• Are trying to lose weight or improve body composition

• Have blood sugar issues or frequent cravings

• Feel constantly tired or recovering from illness

• Are doing strength or resistance training

Protein Shakes for Weight Loss and Energy

When used properly, protein shakes can help you feel fuller for longer, stabilise blood sugar, reduce cravings, and support muscle tone. All of this is especially important if you’re trying to lose weight, increase energy, or support hormonal health in your 40s and beyond.

Just be mindful of what you blend into your shake. Stick to low-sugar fruits, greens, and healthy fats like flax or chia seeds, and be aware of calorie-rich extras.

FAQ – Your Protein Powder Questions Answered

1. Do I need a protein powder if I eat healthily?
Possibly. Many women over 40 struggle to get enough protein from food alone. A powder can fill the gap without adding cooking stress.

2. What’s the best time to have my protein shake?
It depends on your routine. A protein-rich breakfast can help stabilise blood sugar, while post-exercise is ideal for muscle support. You can also use it as a snack to avoid mid-afternoon energy crashes.

3. Will it make me bulky?
Not at all. Protein helps preserve lean tissue, which supports metabolism and tone—not bulk. Women do not have the same hormonal profile as men to build large muscles from diet alone.

4. What if I feel bloated after taking it?
Look at the ingredients. Some powders contain gums, fillers, or sugar alcohols that can cause digestive upset. Switching to a cleaner option or trying a different protein source can make a big difference.

5. Can I use protein powder every day?
Yes, if it suits you. Many of my clients include it daily—especially at breakfast or after exercise. Just make sure it complements, rather than replaces, a healthy, whole-food diet.

6. Can it help with menopausal symptoms?
Yes, it can help manage energy, cravings, mood swings, and weight changes, all of which are common during menopause. It also supports muscle and bone strength—two key concerns in the 40+ years.

Choosing the right protein powder isn’t about perfection—it’s about finding what works for your body and lifestyle. Start small, look for transparency in labelling, and use it as a tool to support your energy, body composition, and hormone health.
